Benefits of technology

[0003] The typical system described above performs extremely well in terms of its ability to permit each individual photograph to be finished as necessary to achieve a quality print. However, at photo studi

Problems solved by technology

However, at photo studios or other such sites dealing with commercial or professional photographic prints, in addition to such capabilities, there is uncompromising demand for ability to attain satisfactory color during printing.
But it is not an easy matter to attain satisfactory color during printing.
Despite this, conventional systems do not possess the capa

Embodiment Construction

[0031] Before beginning description of embodiments, “color profiles” and “color matching,” repeated reference to which is made throughout such description, will be described.

[0032] Each of the various image processing devices (e.g., cameras, image scanners, display monitors, printers, etc.) has its own unique color space(s) in which operations are carried out and its own unique gamut(s), i.e., locus or loci of colors that can be created. For example, while display monitors all operate within RGB color space, gamut will vary from monitor to monitor. Likewise, gamuts of printers, which carry out operations in CMYK color space, will be different for different printers. Furthermore, even the same printer will exhibit different gamuts depending upon the type of ink and printing medium (printing paper) used therewith.

[0033]FIG. 1 is drawing showing a schematic example of gamuts of different devices. At FIG. 1, reference numeral 300 indicates gamut visibly perceivable by human beings, re...

Abstract

Provided is color printing technology capable of accommodating variation(s) in printer color space(s). User(s) may place test pattern printout(s) 336 and test pattern master sheet(s) 337 next to each other on platen(s) of image scanner(s) 338, and may cause image scanner(s) 338 to scan such printout(s) 336 and master sheet(s) 337 in a single image scanning run. Captured image data output from image scanner(s) 338 may be acquired by print server machine(s) 2 and may be uploaded to center server machine(s) 8. Center server machine(s) 8 is or are such that any difference(s) in color(s) between test pattern printout(s) 336 and master sheet(s) 337 is or are detected based on such uploaded captured image data; furthermore, based on results of such detection, new printer ICC profile(s) is or are created which represents or represent the current color space(s) of printer(s) 3A, 3B being investigated, and corresponding printer ICC profile(s) within printer ICC profile database 330 is or are updated

Description

FIELD OF ART [0001] The present invention relates generally to a printing system employing computer(s) and electronic printer(s), and pertains more particularly to a printing system suited to operations, from the taking of photograph(s) to the printing thereof, taking place at photo studio(s). BACKGROUND ART [0002] As a result of improvements in digital camera and electronic printer performance, not only amateurs but also photographic industry professionals have begun using digital cameras and electronic printers. Amateurs as well as professionals typically make use of a simple system wherein an electronic printer is connected by way of a dedicated interface cable, LAN, or the like to a personal computer on which a photo retouching program is installed. Use of a sophisticated photo retouching program makes it possible to carry out a diverse variety of retouching and / or color correction operations on photographic images taken with a digital camera, and / or freely vary the size and / or ...
